It fits the original battery slot directly, using OEM part references BA S850, 35H00194-00M, 99H10905-00, and BL01100. If your Desire C no longer holds charge through a normal day, this cell restores the capacity the original had when new.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDesire C and A320E compatibility:\u003c\/strong\u003e\n    Both the Desire C and A320E share the same battery bay geometry, voltage rail, and connector pinout — one cell fits both variants without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the Desire C platform. The BMS handshake completed correctly, charge termination triggered at 4.2V, and the protection circuit responded to over-discharge conditions as expected.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge to automatic shutdown followed by an uninterrupted charge to 100% before using the phone normally. The Desire C's fuel gauge IC calibrates its coulomb counter against the actual cell discharge curve on that first full cycle — skipping it causes the percentage readout to drift.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the Desire C after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Desire C uses a fuel gauge IC that was calibrated to the original cell's internal resistance profile. A new cell with different impedance characteristics can cause the gauge to misread the remaining charge, triggering an abrupt shutdown before the display reaches 0%. The phone cuts power because the voltage drops below the BMS protection threshold under load — even though the gauge still shows charge remaining. Running one complete discharge-charge cycle after installation lets the IC update its internal model to match the new cell, which eliminates most premature shutdowns.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone won't power on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge in storage, and if this battery was stored for an extended period before installation, the cell voltage may have dropped below 2.5V per cell — the threshold at which the BMS enters lockout to prevent damage. Plugging in the charger may show no response at all. Leave the phone connected to a wall charger, not a computer USB port, for 20–30 minutes without pressing the power button. Once the cell recovers above the BMS re-enable threshold, the phone will begin a normal charge cycle and power on.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405009551450,"sku":"BWCS-HTA320XL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405009584218,"sku":"BWCS-HTA320XL-2","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405009616986,"sku":"BWCS-HTA320XL-3","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HTA320XL-1.webp?v=1779369805","url":"https:\/\/batteryweb.com\/products\/htc-desire-c-replacement-battery-37v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
